Sale Order add produced by-products
This module extends the functionality of Manufacturing Orders to automatically transfer produced by-products to the associated Sale Order once the Manufacturing Order is closed. This allows for easier invoicing and management of by-products sold to customers.
Key Features
Automatically adds/updates Sale Order Lines for by-products when a Manufacturing Order is marked as ‘done’.
Prevents additional Manufacturing Orders or procurements from being triggered for these by-product lines, as they are a result of existing production.
Ensures accurate tracking of by-product quantities on the Sale Order for invoicing purposes.

Use Cases / Context
Business Use Case: By-product Invoicing for Contract Manufacturers
This module is designed for contract manufacturing scenarios where the client provides raw materials or a base product for processing. Unlike standard manufacturing where the output quantity of finished goods is precisely known, this use case involves a process where the exact yield of by-products is uncertain until after the manufacturing operation is complete.
Scenario
A contract manufacturer processes materials supplied by a client. During this process, in addition to any primary output, a variable quantity of by-products is inevitably generated. The client is obligated to purchase these by-products from the contract manufacturer.
Problem
At the time of sale order creation, it is impossible to accurately determine the quantity of by-products that will be produced from the manufacturing process. Therefore, these by-products cannot be initially included on the sales order for invoicing. Traditional Odoo MRP workflows are designed for planned production, not for dynamic by-product quantification for sales.
Solution
This module automates the process of adding the actual, measured quantities of produced by-products to the corresponding sales order. Once the Manufacturing Order (MO) for the client’s material is completed (marked as ‘done’):
The module identifies all by-products that were actually produced during that specific MO.
It filters these by-products, adding only those that are configured as “Can be Sold” (``sale_ok=True``).
It then adds these filtered by-products, along with their actual quantities, as new lines (or updates existing lines) on the original sales order linked to that MO.
These by-product lines are flagged to ensure they do not trigger new manufacturing orders or procurement requests, as their supply comes directly from the completed production.
Benefits
Accurate Invoicing: Ensures clients are correctly billed for all by-products generated during the contract manufacturing process, preventing revenue loss.
Streamlined Operations: Automates the manual task of reconciling by-product quantities and adding them to sales orders.
Improved Traceability: Maintains a clear link between the manufacturing process and the resulting by-product sales.
Enhanced Reporting: Allows for better reporting on by-product yields and sales for analysis and compliance.
Configuration
No specific configuration is required for this module to function, beyond the standard Odoo setup for Manufacturing Orders, Bills of Materials (BOMs), and Products.
However, for optimal use:
By-product Products: Ensure your by-product products are correctly defined in Odoo, ideally belonging to a specific product category (e.g., ‘By-products’).
Crucially, the by-product product must have its “Can be Sold” (``sale_ok``) field set to ``True`` in its product form under the “Sales” tab. By-products with sale_ok = False will be ignored by this module and will not be added to the Sales Order.
BOMs with By-products: Your Bills of Materials (BOMs) for your main manufactured products must have the relevant by-products configured under the “By-products” tab with their planned quantities.
Usage
Create a Sales Order (SO) for the main product that your client will receive.
The main product should have a Bill of Materials (BOM) defined that includes the by-products under its “By-products” tab.
The main product’s inventory route should be configured for “Manufacture” (or “Make to Order” if applicable).
Confirm the Sales Order. This will automatically generate a Manufacturing Order (MO) for the main product.
Process the Manufacturing Order:
Navigate to the generated Manufacturing Order.
Ensure all necessary raw materials are available.
Move the MO through its production stages (e.g., confirm, plan, start production, consume components).
Crucially, ensure the actual quantities produced for the by-products are recorded on the MO’s respective moves (e.g., on the stock.move records associated with the by-products, typically under the ‘Finished Products’ or ‘By-products’ tab of the MO, the ‘Done’ quantity should reflect the actual yield).
Mark the Manufacturing Order as Done. This is the trigger for the module’s automation.
Verify the Sales Order:
Go back to the Sales Order that was linked to the completed MO.
You will find new line(s) added (or existing lines updated) for the by-product(s) with their actual produced quantities from the MO.
These by-product lines will be flagged internally (is_mrp_byproduct_line = True) to prevent them from triggering new, unnecessary manufacturing orders or procurement requests.
Invoice the Client: You can now proceed to create an invoice from the Sales Order, which will include the by-products for billing to your client.
This automated process ensures that clients are accurately billed for all by-products generated during the contract manufacturing process.
